Learning with Assistance Systems

Not Seeing the Process for the Tasks?
Gergana Vladova, Philip Wotschack, Patricia de Paiva Lareiro, Norbert Gronau ORCID Icon, Christof Thim
The paper describes the conception and implementation as well as offers an insight into the first results of a study with experimental design in a simulated process environment at the Research and Application Center Industry 4.0 in Potsdam. The focus is on learning processes in the field of simple work and their organization through the use of digital assistance systems. In labour research, there are indications that process knowledge is lost with the use of these systems, in the sense of a good knowledge of the entire work process in which the individual activities are embedded. To investigate the role of process knowledge in the use of digital assistance systems, a real factory situation is simulated in the experiment.

The Digital Control Loop in the Smart Factory

The Digital Control Loop in the Smart Factory

Dennis Schwäke, Axel Hahn, Frank Fürstenau
Production targets in the Smart Factory should be supported by digital control loops. This article will present a concept, which describes the structure of operational information flows as elements of a control loop. The term digital control loop encompasses technical control systems and business processes as well as integrating vertically and horizontally information from business applications. The common alignment of different aspects is adjusted to operational targets along the value added chain. The idea of using the digital control loop as an approach for this, is evaluated in a case study.

The Loop of Cognition

The Loop of Cognition

How “intelligence” is constellated on a silicon basis
Claus Riehle, Thorsten Pötter, Thomas Steckenreiter
In process engineering, one thinks of production operations that are controlled or regulated by sensors and actuators. And any realization of matter transformation is based on a physical substratum, which holds equally for living systems and their behaviour. The article distinguishes between three system levels: the functional level, the interface to the environment and the cognitive level of. Using these three levels, the learning cycle or the previous Cognitive Loop can be very well illustrated. If one compares with this way of distinction the Bio-Informatization of human intelligence with the technical development stages of mechanization, automation, regulation and deep learning, then the cybernetic-sociological term “operational closure” becomes understandable. It becomes obvious that in the context of a digitized culture of production and organization, we should be prepared for a new kind of cognitive loop based on silicon (SI), an intelligent system behavior via ...

What Role Does Real Human-Robot-Collaboration Truly Play in Manufacturing Companies?

What Role Does Real Human-Robot-Collaboration Truly Play in Manufacturing Companies?

Welche Rolle spielt die Mensch-Roboter-Kollaboration in der Praxis?
Tobias Kopp ORCID Icon, Arndt Schäfer, Steffen Kinkel ORCID Icon
Collaborative robots (so-called cobots) that enable secure hand-in-hand collaboration with construction workers without physical separation are regarded as a promising future technology for manufacturing companies. In practice, there are some cases in which people interact with cobots, but very few in which collaboration in a narrower sense takes place. What are the reasons for this lack of collaborative applications? What role does the cobots’ ability to enable collaboration play in practice? The study is based on qualitative evidence gathered in four German small and medium-sized enterprises (SMEs).

Modular Digital Twin for Adaptive Systems

Modular Digital Twin for Adaptive Systems

Human-machine interaction for control of semi-autonomous systems for container unloading
Jasper Wilhelm, Christoph Petzoldt, Thies Beinke, Michael Freitag ORCID Icon
The use of autonomous systems is not efficient in all applications due to variable system environments or small quantities. Semi-autonomous systems are able to bridge this gap. This article presents a digital twin-based approach for human-machine interaction using adaptive automation. A case study shows how a modular digital twin can support the operator of a CPS in specific tasks. This method allows for a distinction between short-term signal changes and long-term behavior modification. Thus, semi-autonomous systems can support operators in scenarios in which autonomous systems are not viable.

Challenges in Dealing with Production Disturbances

Challenges in Dealing with Production Disturbances

Results of a survey on the current state of disturbance management
Norbert Gronau ORCID Icon, Eva-Maria Kern, Hendrik Jonitz
Current State of Disturbance Management Disturbances in production systems can lead to massive costs for enterprises. It is a highly relevant ability for manufacturing companies to cope with the effects of occurring disturbances and their prevention. A survey on manufacturing companies draws a current picture of disturbance management and identifies challenges for coping with disturbances.

Ultrasonic Welding of Biodegradable Plastic Films

Ultrasonic Welding of Biodegradable Plastic Films

Untersuchung biobasierter Kunststoffbeutel für die Handhabung von Trockeneis im TK-Lebensmittelversand
Michael Lütjen ORCID Icon, Jannik Fechner, Michael Freitag ORCID Icon, Maximilian Podein
The food distribution of (deep) refrigerated goods is a steadily growing market segment that deals with sustainability in particular. Due to the high efficiency of the CEP service providers, a shipment as such is not necessarily worse than a shopping trip by car over several kilometers in town. A concrete approach to improve ecological sustainability in food delivery is the substitution of existing PE plastic bags filled with dry ice. The bags help to keep the dry ice together and protect the customer from burns. The following article analyzes ecological aspects of food shipment and conveys an understanding of current development concerning biodegradable plastic films. Due to special material properties of bio-based plastic films, the manufacturability of dry ice bags was investigated in a series of experiments. Dry ice bags were manufactured by means of the very precisely adjustable joining technology ultrasonic welding. Subsequent, load capacity of the dry ice bags was examined.

Smart Objects – A Smart Alternative to Isolated Applications

Smart Objects - A Smart Alternative to Isolated Applications

von der Planung bis zum Betrieb
Timur Ripke, Sven Kägebein
Media disruption interferes with consistent and universal digitalization. Data is easily lost, time and resources wasted. Heterogeneous and isolated applications produce partial relief; however they fail to integrate redundant information from separately operated systems into a homogeneously processible data mass. The employment of a centralized data hub proposes a strategy to effectively advance digitalization in process management, connecting scheduling of involved parties, defect tracking and progress processes. It also automatizes reportings on project progress.

Smart Service Lifecycle Management

Smart Service Lifecycle Management

Rahmenkonzept und Anwendungsfall
Mike Freitag, Stefan Wiesner
The growing amount of available data due to the digitalization of value creation is accelerating the transformation of manufacturing industries into providers of customer-oriented services. Smart services, currently the most highly developed level of data-based digital services to complement physical products for specific customer expectations, are an example of this. However, the analysis of expert interviews as well as of use cases from business practice shows that the knowledge of how such smart services can be developed is still rudimentary. This article presents a framework for Smart Service Lifecycle Management that supports the systematic development of Smart Services, taking into account business models and the value network. The framework concept will be implemented and validated based on an application example from the textile industry.

Industrie 4.0 and Lean Production Systems

Industrie 4.0 and Lean Production Systems

Interdependencies and Use-Case Analysis
Uwe Dombrowski, Thomas Richter, Fabian Loerwald
The complexity of the production process and the higher demand for quality and individualization leads to structural changes and challenges in the production process. The analysis of interdependencies of Lean Production Systems as an industrial standard und Industrie 4.0 is able to determine new spaces of action and alternative solutions to optimize the production processes. The analysis shows that the technologies and systems of Industrie 4.0 does not compete but rather support the principles of Lean Production Systems.
